form_tag

Starts a form tag that points the action to an url configured with url_for_options just like ActionController::Base#url_for. The method for the form defaults to POST.

Options

• :multipart - If set to true, the enctype is set to "multipart/form-data".
• :method - The method to use when submitting the form, usually either "get" or "post". If "put", "delete", or another verb is used, a hidden input with name _method is added to simulate the verb over post.
• A list of parameters to feed to the URL the form will be posted to.

Examples

  form_tag('/posts')
  # => <form action="/posts" method="post">

  form_tag('/posts/1', :method => :put)
  # => <form action="/posts/1" method="put">

  form_tag('/upload', :multipart => true)
  # => <form action="/upload" method="post" enctype="multipart/form-data">

  <% form_tag '/posts' do -%>
    <div><%= submit_tag 'Save' %></div>
  <% end -%>
  # => <form action="/posts" method="post"><div><input type="submit" name="submit" value="Save" /></div></form>
